Assisting user in managing a calendar application

ABSTRACT

A method, system and computer program product for managing a calendar application. A need to optimize a calendar is identified. Furthermore, a period of time to optimize the calendar is received or identified. All the scheduled events (e.g., scheduled meetings) in the calendar are then selected during that period of time. The attendees, topics and flags, if any, for each of the selected scheduled events during the period of time are extracted. Prior collaborations with the user involving the extracted attendees and/or topics of the selected scheduled events are identified. Collaboration data (e.g., participants/senders/attendees, topics) is then extracted from the identified prior collaborations. A list of actions (e.g., delegate scheduled event to another user) is generated to be performed on a selected scheduled event based on the extracted collaboration data. The generated list of actions to be performed on the selected scheduled event is then presented to the user.

TECHNICAL FIELD

The present invention relates generally to calendaring systems, and more particularly to assisting the user in managing a calendar application.

BACKGROUND

Calendaring systems, in the simplest form, help users to organize their time. Additionally, calendaring systems may be used to schedule meetings, appointments, vacations or other types of calendar events or activities.

However, users may have difficulty in managing their calendar, which may include numerous meetings, activities, etc. At times, some of these scheduled events may overlap other scheduled events. Furthermore, some of these scheduled events may even be duplicates. As a result, users may have to spend time in determining how to address the overlapped or duplicate scheduled events resulting in loss of time and frustration.

Furthermore, if a user desires to take a vacation but there are numerous previously scheduled events during the time the user desires to take a vacation, then the user will have to spend time in resolving the conflicts resulting in further loss of time and frustration.

Currently, calendaring systems do not assist the user in managing the user's calendar to address such situations.

SUMMARY

In one embodiment of the present invention, a method for managing a calendar application comprises identifying a need to optimize a calendar. The method further comprises receiving or identifying a period of time to optimize the calendar. The method additionally comprises selecting all scheduled events in the calendar during the period of time. Furthermore, the method comprises extracting, by a processor, attendees and topics for each selected scheduled event during the period of time. Additionally, the method comprises identifying, by the processor, prior collaborations with a user of the calendar involving the extracted attendees and/or topics of the selected scheduled events. In addition, the method comprises extracting, by the processor, collaboration data from the identified prior collaborations. The method further comprises generating a list of actions to be performed on a scheduled event of the selected scheduled events based on the extracted collaboration data. The method additionally comprises presenting the generated list of actions to the user of the calendar to be performed on the scheduled event.

Other forms of the embodiment of the method described above are in a system and in a computer program product.

The foregoing has outlined rather generally the features and technical advantages of one or more embodiments of the present invention in order that the detailed description of the present invention that follows may be better understood.

DETAILED DESCRIPTION

The present invention comprises a method, system and computer program product for managing a calendar application. In one embodiment of the present invention, a calendar client agent identifies a need to optimize a calendar. For example, the client calendar agent may determine that there is a need to optimize the user's calendar based on detecting an overlap of scheduled events. A period of time to optimize the calendar is received or identified by the client calendar agent (e.g., the period of time in which the scheduled events overlap). Client calendar agent then selects all the scheduled events (e.g., scheduled meetings, scheduled appointments) in the calendar during that period of time. The attendees, topics and flags, if any, for each of these selected scheduled events during the period of time are extracted by the calendar client agent. Prior collaborations with the user involving the extracted attendees and/or topics of the selected scheduled events are identified by the calendar client agent. For example, such prior collaborations with the user may involve social media posts, e-mail messages, instant messages and previously scheduled calendar events with the user. Collaboration data is then extracted from the identified prior collaborations by the calendar client agent. “Collaboration data,” as used herein, refers to data concerning the interaction between the user and others involving an activity (e.g., work activity, such as a meeting, social activity). Examples of such collaboration data include the names of the participants/senders/attendees in the social media posts, e-mail messages, instant messages and previously scheduled calendar events as well as the topics of such prior collaborations. A list of actions may then be generated to be performed on a selected scheduled event based on the extracted collaboration data. For example, the list of actions may include delegating the scheduled event to another user who engaged in a prior collaboration with the user involving a topic within a threshold degree of similarity as the topic of the scheduled event. The generated list of actions to be performed on the scheduled event is then presented to the user. In this manner, the user is provided an opportunity to select an action (e.g., delegating the scheduled meeting to another user) to optimize the calendar to address situations, such as having an excessive number of scheduled events over a period of time, an overlap of scheduled events over a period of time, a duplicate scheduled event, scheduling a vacation during a time in which events have previously been scheduled, having an excessive amount of work to be accomplished, etc.

In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without such specific details. In other instances, well-known circuits have been shown in block diagram form in order not to obscure the present invention in unnecessary detail. For the most part, details considering timing considerations and the like have been omitted inasmuch as such details are not necessary to obtain a complete understanding of the present invention and are within the skills of persons of ordinary skill in the relevant art.

Referring now to the Figures in detail, FIG. 1 illustrates a communication system 100 for practicing the principles of the present invention in accordance with an embodiment of the present invention.

While FIG. 1 illustrates a single social network server 110, it is noted for clarity that multiple servers may be used to implement the social networking and/or microblogging service.

System 100 is not to be limited in scope to any one particular network architecture. System 100 may include any number of computing devices 101, servers 102, networks 103 and social network servers 110.

Referring now to FIG. 2, FIG. 2 illustrates a hardware configuration of computing device 101 (FIG. 1) which is representative of a hardware environment for practicing the present invention. Referring to FIG. 2, computing device 101 has a processor 201 coupled to various other components by system bus 202. An operating system 203 runs on processor 201 and provides control and coordinates the functions of the various components of FIG. 2. An application 204 in accordance with the principles of the present invention runs in conjunction with operating system 203 and provides calls to operating system 203 where the calls implement the various functions or services to be performed by application 204. Application 204 may include, for example, a calendar application as well as calendar client agent 106 (FIG. 1) for assisting the user in managing a calendar application as discussed further below in connection with FIGS. 3-5.

Referring again to FIG. 2, read-only memory (“ROM”) 205 is coupled to system bus 202 and includes a basic input/output system (“BIOS”) that controls certain basic functions of computing device 101. Random access memory (“RAM”) 206 and disk adapter 207 are also coupled to system bus 202. It should be noted that software components including operating system 203 and application 204 may be loaded into RAM 206, which may be computing device's 101 main memory for execution. Disk adapter 207 may be an integrated drive electronics (“IDE”) adapter that communicates with a disk unit 208, e.g., disk drive.

Computing device 101 may further include a communications adapter 209 coupled to bus 202.

In this manner, a user is capable of inputting to computing device 101 through keyboard 212 or mouse 213 and receiving output from computing device 101 via display 215 or speaker 214. Other input mechanisms may be used to input data to computing device 101 that are not shown in FIG. 2, such as display 215 having touch-screen capability and keyboard 212 being a virtual keyboard. Computing device 101 of FIG. 2 is not to be limited in scope to the elements depicted in FIG. 2 and may include fewer or additional elements than depicted in FIG. 2.

The present invention may be a system, a method, and/or a computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.

The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.

Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.

Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++ or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.

Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.

These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.

The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.

The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.

As stated in the Background section, calendaring systems, in the simplest form, help users to organize their time. Additionally, calendaring systems may be used to schedule meetings, appointments, vacations or other types of calendar events or activities. However, users may have difficulty in managing their calendar, which may include numerous meetings, activities, etc. At times, some of these scheduled events may overlap other scheduled events. Furthermore, some of these scheduled events may even be duplicates. As a result, users may have to spend time in determining how to address the overlapped or duplicate scheduled events resulting in loss of time and frustration. Furthermore, if a user desires to take a vacation but there are numerous previously scheduled events during the time the user desires to take a vacation, then the user will have to spend time in resolving the conflicts resulting in further loss of time and frustration. Currently, calendaring systems do not assist the user in managing the user's calendar to address such situations.

The principles of the present invention provide a means for assisting the user in managing a calendar application to address such situations as discussed below in connection with FIGS. 3-5. FIG. 3 is a flowchart of a method for assisting the user in managing a calendar application. FIG. 4 illustrates multiple overlapped scheduled events. FIG. 5 illustrates presenting to the user of the calendar application the option of delegating a scheduled event to another user.

As stated above, FIG. 3 is a flowchart of a method 300 for assisting user 101 (FIG. 1) in managing a calendar application in accordance with an embodiment of the present invention.

Referring to FIG. 3, in conjunction with FIGS. 1-2, in step 301, a determination is made by calendar client agent 106 as to whether there is a need to optimize the user's calendar. In one embodiment, such a determination is made by calendar client agent 106 obtaining calendar information from the user's calendar application (e.g., Google® Calendar) via the calendar application's application programming interface (API).

For example, calendar client agent 106 may determine that there is a need to optimize the user's calendar based on the number of scheduled events (e.g., scheduled meetings, scheduled activities, scheduled appointments, scheduled vacations) exceeding a threshold number over a period of time. In another example, calendar client agent 106 may determine that there is a need to optimize the user's calendar based on detecting an overlap of scheduled events over a period of time. In a further example, calendar client agent 106 may determine that there is a need to optimize the user's calendar based on detecting a vacation. In another example, calendar client agent 106 may determine that there is a need to optimize the user's calendar based on detecting a duplicate scheduled event. In a further example, calendar client agent 106 may determine that there is a need to optimize the user's calendar based on a metric (commonly referred to as “velocity”) for how much work is expected to be accomplished for the user (or an organization, group or team involving the user) over a period of time exceeding a threshold number.

If a need has not been identified to optimize the user's calendar, then calendar client agent 106 continues to determine whether there is a need to optimize the user's calendar in step 301.

If, however, a need has been identified to optimize the user's calendar, then, in step 302, calendar client agent 106 receives or identifies a period of time to optimize the calendar. In one embodiment, calendar client agent 106 receives a period of time from the user via a user interface of computing device 101. In one embodiment, calendar client agent 106 determines the period of time to optimize the calendar based on the period of time calendar client agent 106 determined that a need existed to optimize the calendar as discussed above in connection with step 301. For example, calendar client agent 106 may have detected overlapped scheduled events over a four hour window of time. In another example, calendar client agent 106 may have detected a scheduled vacation for this coming Monday. Such period of times may correspond to the period of time to optimize the calendar.

In step 303, calendar client agent 106 selects all the scheduled events in the calendar during the period of time. As discussed above, calendar client agent 106 may extract the calendar information (e.g., scheduled events over a period of time) from the user's calendar application (e.g., Google® Calendar) via the calendar application's application programming interface (API). For example, calendar client agent 106 may select all the scheduled events during a three hour window of time involving overlapped scheduled events as shown in FIG. 4.

FIG. 4 illustrates multiple overlapped scheduled events in accordance with an embodiment of the present invention. Referring to FIG. 4, user interface 400 (displayed on the user interface of computing device 101) illustrates five overlapped scheduled events (e.g., meetings). For example, meeting 1 is scheduled from 9:00-11:00, meeting 2 is scheduled from 9:00-11:30, meeting 3 is scheduled from 9:30-10:00, meeting 4 is scheduled from 10:00-10:30 and meeting 5 is scheduled from 11:00-12:00. These scheduled events are selected to be optimized by calendar client agent 106 due to the fact that their scheduled times overlap one another.

Returning to FIG. 3, in conjunction with FIGS. 1-2 and 4, in step 304, calendar client agent 106 extracts the attendees, topics and flags, if any, for each selected scheduled event during the period of time obtained in step 302. Attendees, as used herein, refer to those who are present at an event, meeting, etc., or at a particular place.

In one embodiment, the attendees (e.g., invitees) for each selected scheduled event are extracted from the calendar information obtained from the user's calendar application (e.g., Google® Calendar) via the calendar application's application programming interface (API). Such attendees may include those that are required to attend the scheduled event as well as those that are optionally invited to attend, such as via the carbon copy option, or are just informed, such as via the blind carbon copy option.

In one embodiment, the topic is extracted for each selected scheduled event using natural language processing. For example, calendar client agent 106 may utilize natural language processing to identify keywords in the description of the scheduled event (e.g., meeting) obtained from the calendar information extracted from the user's calendar application. For instance, if the description of meeting 1 of FIG. 4 is “teleconference call with Examiner regarding patent application involving references teaching growing crystalline semiconductor oxide thin films on a substrate,” then calendar client agent 106 may identify keywords, such as “teleconference call with Examiner,” “regarding patent application” and “growing . . . thin films on a substrate” using natural language processing to identify topics, such as teleconference call with Examiner, patent application and growing thin films on a substrate. In one embodiment, the keywords may be any natural language element.

Furthermore, in one embodiment, calendar client agent extracts the flags (e.g., confidential, personal), if any, for each selected scheduled event from the calendar information obtained from the user's calendar application (e.g., Google® Calendar) via the calendar application's application programming interface (API). In one embodiment, appropriate action is taken by client calendar agent 106 in response to identifying particular flags (e.g., confidential) that indicate special user action. For example, a confidential meeting will only be recommended to be reassigned to other users who are authorized to participate in the confidential meeting in attempting to optimize the user's calendar as discussed below. In another example, a flag may indicate restrictions in forwarding or delegating the scheduled event. In another example, a flag may indicate processing restrictions, such as restrictions in processing calendar requests.

In step 305, calendar client agent 106 identifies prior collaborations with user 101 (user of the calendar application) involving the extracted attendees and/or topics of the selected scheduled events. In one embodiment, such prior collaborations with user 101 involve social media posts, e-mail messages, instant messages and previously scheduled calendar events with user 101.

In step 306, calendar client agent 106 extracts collaboration data from the identified prior collaborations. “Collaboration data,” as used herein, refers to data concerning the interaction between user 101 and others involving an activity (e.g., work activity, such as a meeting, social activity). Examples of such collaboration data include the names of the participants/senders/attendees in the social media posts, e-mail messages, instant messages and previously scheduled calendar events as well as the topics of such prior collaborations.

In one embodiment, calendar client agent 106 utilizes natural language processing to identify topics of interest for social media posts, e-mail messages, instant messages, etc. received by user 101. For instance, calendar client agent 106 using natural language processing may identify keywords (e.g., “growing thin films on a substrate”) in an e-mail message regarding a patent application prosecuted by user 101.

In another embodiment, calendar client agent 106 utilizes natural language processing to identify topics of interest in previously scheduled calendar events with user 101.

In another embodiment, calendar client agent 106 extracts the names of the participants/senders/attendees in the social media posts, e-mail messages, instant messages and previously scheduled calendar events.

For one of the scheduled events out of the selected scheduled events that needs to be addressed during the period of time obtained in step 302, in step 307, calendar client agent 106 generates a list of actions to be performed on the scheduled event based on the extracted collaboration data. For example, the list of actions may include delegating the scheduled event to another user 101 (e.g., an attendee of the scheduled event) who engaged in a prior collaboration with user 101 (user of the calendar) involving a topic within a threshold degree of similarity as the topic of the scheduled event. For instance, client calendar agent 106 may determine that a second user 101 sent an e-mail message to a first user 101 involving the topic of growing thin films on a substrate. If client calendar agent 106 had previously determined that the first user 101 has a meeting involving a teleconference with an Examiner regarding references involving growing thin films on a substrate and the scheduled time of such a meeting overlaps another scheduled meeting, then client calendar agent 106 may recommend to delegate the scheduled meeting with the Examiner to the second user 101 as discussed further below.

In one embodiment, the topic of the scheduled event and the topic of the prior collaboration (e.g., prior e-mail correspondence) are determined using natural language processing. In one embodiment, the degree of similarity of the topic of the scheduled event and the topic of the prior collaboration (e.g., prior e-mail correspondence) is based, at least in part, on how close in meaning are the topics of the scheduled event and the prior collaboration. In one embodiment, the threshold used in the threshold degree of similarity is user provided.

In another example, the list of actions may include cancelling the scheduled event, declining the scheduled event, delegating the scheduled meeting to a team, reducing a number of attendees of the scheduled event, increasing a number of attendees of the scheduled event, reassigning chairmanship (organizer) of the scheduled event, etc.

In one embodiment, another user 101 (e.g., user 101B) may only be selected to delegate a scheduled event for user 101 (e.g., user 101A) if that user 101 (e.g., user 101B) had a threshold number of interactions with user 101 (e.g., user 101A) involving the topic of the scheduled event.

In one embodiment, another user 101 (e.g., user 101A) may only be selected to delegate a scheduled event for user 101 (e.g., user 101A) if that user 101 (e.g., user 101B) is a member of the same team, group, etc. as user 101 (e.g., user 101A).

In step 308, calendar client agent 106 presents the generated list of actions to be performed on a scheduled event (e.g., meeting 1 of FIG. 4) to user 101 (user of the calendar application).

In step 309, a determination is made by calendar client agent 106 as to whether it received a selection of an action from the list of actions from user 101.

If calendar client agent 106 does not receive a selection of an action from the list of actions from user 101, then, in step 310, calendar client agent 106 does not perform an action on the scheduled event.

In step 311, a determination is made by calendar client agent 106 as to whether any other scheduled events (out of the selected scheduled events) need to be addressed. For example, referring to FIG. 4, if meeting 1 was the only scheduled event that was addressed, then the other scheduled events (e.g., meetings 2-5) with a scheduled time that overlap one another still need to be addressed.

If there are other scheduled events that need to be addressed, then calendar client agent 106 generates a list of actions to be performed on a scheduled event out of the selected scheduled events based on the extracted collaboration data in step 307.

If, however, there are no other scheduled events that need to be addressed, then calendar client agent 106 continues to determine whether there is a need to optimize the user's calendar in step 301.

Returning to step 309, if, however, calendar client agent 106 received a selection of an action from the list of actions from user 101, then, in step 312, calendar client agent 106 performs the selected action on the scheduled event as illustrated in FIG. 5.

FIG. 5 illustrates presenting to user 101 (user of the calendar application) on user interface 500 (displayed on the user interface of computing device 101) the option of delegating a scheduled event to another user 101 in accordance with an embodiment of the present invention.

As illustrated in FIG. 5, user 101 is presented an option with assigning or delegating meeting 1 to a different user (e.g., user A) to address the situation where meeting 1 is scheduled during a time that other meetings were scheduled as discussed in FIG. 4.

Referring to the example discussed above, if client calendar agent 106 had previously determined that the first user 101 has a meeting involving a teleconference with an Examiner regarding references involving growing thin films on a substrate and the scheduled time of such a meeting overlaps another scheduled meeting, then client calendar agent 106 may recommend to delegate the scheduled meeting with the Examiner to the second user 101. In such a situation, client calendar agent 106 may recommend to the first user 101 to delegate the scheduled meeting to the second user 101, such as shown in FIG. 5.

As illustrated in FIG. 5, in one embodiment, user 101 is provided the option of accepting or declining (see accept button 501 and decline button 502, respectively, in FIG. 5) the option of assigning or delegating meeting 1 to a different user as shown in FIG. 5.

In one embodiment, if user 101 selects the option of delegating the scheduled event to another user, such as via selecting accept button 501, then client calendar agent 106 forwards an invitation to that user to delegate that scheduled event.

Other actions that may be performed to optimize the calendar include cancelling the scheduled event, declining the scheduled event, delegating the scheduled meeting to a team, reducing a number of attendees of the scheduled event, increasing a number of attendees of the scheduled event, reassigning chairmanship (organizer) of the scheduled event, etc. By implementing these actions, user 101 will be able to optimize the calendar to address situations, such as having an excessive number of scheduled events over a period of time, an overlap of scheduled events over a period of time, a duplicate scheduled event, scheduling a vacation during a time in which events have previously been scheduled, having an excessive amount of work to be accomplished, etc. By using computing technology to identify such situations and to utilize collaboration data from prior collaborations with the user, various actions may be proposed to the user to address such situations. In this manner, the functionality of calendaring systems is improved by allowing the user to better manage the user's scheduled events in the user's calendar.

Returning to FIG. 3, in conjunction with FIGS. 1-2 and 4-5, after performing the selected action on the scheduled event, calendar client agent 106 determines whether any other scheduled events (out of the selected scheduled events) need to be addressed in step 311.
